BACKGROUND OF THE PRESENT INVENTION Field of the Present Invention

The present invention relates generally to electronic equipment cabinetstructures and enclosures, and, in particular, to rail seals forinstalling on vertical mounting rails in electronic equipment cabinetstructures and enclosures.

Background

Racks, frames and cabinets for mounting and storing electroniccomponents have been well known for many years. Frames and racks aretypically simple rectangular frameworks on which electronic componentsmay be mounted, or on which other mounting members, such as shelves orbrackets, may be mounted which in turn may support the electroniccomponents. Cabinets are typically frames on which panels or doors, orboth, are hung to provide aesthetic improvement, to protect thecomponents from external influences, to provide security for thecomponents stored inside, or for other reasons. Racks, frames andcabinets (sometimes collectively referred to hereinafter as“enclosures”) are often customized in order to best accommodate thecomponents which they are designed to store.

Air dam kits are commonly installed in an enclosure in order toestablish a barrier between interior portions of the enclosure. In sodoing, air dam kits are used to direct air flow within the enclosure tocool equipment installed therein. Many known air dam kits involve bulky,three-dimensional structures that are often difficult to install withinan enclosure during initial set-up and are particularly difficult toretrofit into an existing enclosure. In a retrofitting process, sidepaneling may need to be removed from the enclosure in order to providethe necessary access point for properly installing the air dam kit.Additionally, known air dam kits can occupy substantial internal spacewithin the enclosure, thereby obstructing the implementation of variouscable routing accessories and equipment and compromising the flexibilityof the enclosure for a wider range of uses.

Accordingly, a need exists for a more efficient type of air dam kit thatoccupies less space within an enclosure and can be installed withrelative ease. Further, a need exists for a type of air dam kit that canbe retrofitted into an existing enclosure through a front access point.Still further, a need exists for a type of air dam kit that is readilyadaptable across a wide range of enclosure features and accessories andcan accommodate front-to-back cable routing.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one havingordinary skill in the relevant art (“Ordinary Artisan”) that the presentinvention has broad utility and application. Furthermore, any embodimentdiscussed and identified as being “preferred” is considered to be partof a best mode contemplated for carrying out the present invention.Other embodiments also may be discussed for additional illustrativepurposes in providing a full and enabling disclosure of the presentinvention. Moreover, many embodiments, such as adaptations, variations,modifications, and equivalent arrangements, will be implicitly disclosedby the embodiments described herein and fall within the scope of thepresent invention.

Accordingly, while the present invention is described herein in detailin relation to one or more embodiments, it is to be understood that thisdisclosure is illustrative and exemplary of the present invention, andis made merely for the purposes of providing a full and enablingdisclosure of the present invention. The detailed disclosure herein ofone or more embodiments is not intended, nor is to be construed, tolimit the scope of patent protection afforded the present invention,which scope is to be defined by the claims and the equivalents thereof.It is not intended that the scope of patent protection afforded thepresent invention be defined by reading into any claim a limitationfound herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps ofvarious processes or methods that are described herein are illustrativeand not restrictive. Accordingly, it should be understood that, althoughsteps of various processes or methods may be shown and described asbeing in a sequence or temporal order, the steps of any such processesor methods are not limited to being carried out in any particularsequence or order, absent an indication otherwise. Indeed, the steps insuch processes or methods generally may be carried out in variousdifferent sequences and orders while still falling within the scope ofthe present invention. Accordingly, it is intended that the scope ofpatent protection afforded the present invention is to be defined by theappended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refersto that which the Ordinary Artisan would understand such term to meanbased on the contextual use of such term herein. To the extent that themeaning of a term used herein—as understood by the Ordinary Artisanbased on the contextual use of such term—differs in any way from anyparticular dictionary definition of such term, it is intended that themeaning of the term as understood by the Ordinary Artisan shouldprevail.

Furthermore, it is important to note that, as used herein, “a” and “an”each generally denotes “at least one,” but does not exclude a pluralityunless the contextual use dictates otherwise. Thus, reference to “apicnic basket having an apple” describes “a picnic basket having atleast one apple” as well as “a picnic basket having apples.” Incontrast, reference to “a picnic basket having a single apple” describes“a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one ofthe items,” but does not exclude a plurality of items of the list. Thus,reference to “a picnic basket having cheese or crackers” describes “apicnic basket having cheese without crackers,” “a picnic basket havingcrackers without cheese,” and “a picnic basket having both cheese andcrackers.” Finally, when used herein to join a list of items, “and”denotes “all of the items of the list.” Thus, reference to “a picnicbasket having cheese and crackers” describes “a picnic basket havingcheese, wherein the picnic basket further has crackers,” as well asdescribes “a picnic basket having crackers, wherein the picnic basketfurther has cheese.”

Referring now to the drawings, in which like numerals represent likecomponents throughout the several views, the preferred embodiments ofthe present invention are next described. The following description ofone or more preferred embodiment(s) is merely exemplary in nature and isin no way intended to limit the invention, its application, or uses.

FIG. 1A is an isometric cross-sectional view of an electronic equipmentenclosure 10, shown with several panels removed to reveal a pair ofvertical mounting rails 30 installed therein, each with a pair of railseals 40 in accordance with one or more preferred embodiments of thepresent invention, and FIG. 1B is a front cross-sectional view of theelectronic equipment enclosure 10 of FIG. 1A, taken along line 1B-1B.The electronic equipment enclosure 10 includes a frame structure 12formed of four vertical support posts 16, upper and lower front crossmembers (not illustrated), upper and lower rear cross members 19,20 andthree pairs of side cross members 21,22,23. Each vertical support post16 includes a plurality of cross member attachment apertures at eachend. Two of the vertical support posts 16 are connected together attheir upper and lower ends by the upper and lower front cross members,respectively, and the other two support posts 16 are connected togetherat their upper and lower ends by the upper and lower rear cross members19,20, respectively. The front cross members and their respectivesupport posts thus define a front frame (not illustrated), and the rearcross members 19,20 and their respective support posts 16 define a rearframe 26. The front and rear frames may be connected together at theirrespective corners by the upper, middle and lower side cross members21,22,23.

Although the particular enclosure 10 and frame structure 12 describedand illustrated herein may include various novel aspects, it will beapparent to the Ordinary Artisan that various aspects of the presentinvention are likewise applicable to enclosures and structures ofgenerally conventional design and construction. Furthermore, variousdifferent connection means may be used to join the various memberstogether. One novel connection means is illustrated in FIG. 1A. However,although not illustrated herein, it will be apparent to the OrdinaryArtisan that in at least some embodiments, any of a variety of otherconnection means may be used instead. In this regard, other examples ofconventional connection means are described in commonly-assigned U.S.Pat. No. 6,185,098, U.S. Pat. No. 7,119,282, U.S. Pat. No. 7,697,285,U.S. Patent Application Publication No. US 2009/0190307 A1, U.S. PatentApplication Publication No. US 2009/0227197 A1, U.S. Patent ApplicationPublication No. US 2009/0283488 A1, and U.S. Patent ApplicationPublication No. US 2010/0172092 A1, the entirety of each of which isincorporated herein by reference. Although likewise not illustratedherein, the precision and the stability of each of the corners of atleast some types of four post frame structures may be enhanced byutilizing a self-squaring corner attachment bracket such as thatdisclosed by the commonly-assigned U.S. Pat. No. 5,997,117 entitled“RACK FRAME CABINET,” the entirety of which is hereby incorporated byreference.

Still further, it will be evident to the Ordinary Artisan that in atleast some embodiments, other structural arrangements may be used toform a frame structure on which panels may be mounted to form anenclosure. For example, in at least one embodiment (not illustrated), aframe structure may be formed from only two support posts.

The enclosure 10 may further include a plurality of panels, attached tothe frame structure 12, which partially or fully enclose the framestructure 12. In contemplated embodiments, the enclosure 10 may includea right and/or left panels 14 (a left panel being illustrated in FIG.1A), a front panel (not illustrated), and a rear panel (notillustrated), one or more of which may be configured to operate as adoor to the interior of the enclosure 10. The enclosure 10 may furtherinclude a bottom panel 17 as well as a generally flat top panel (notillustrated). The top panel may be sized and shaped to fit an openingdefined by the four vertical support posts 16 in connection with theupper front cross member, the upper rear cross member 19, and the upperside cross members 21.
